Specification of Letters Patent.

To all whom 'it imzy concern:

Be tvknown that Vfnnnmr B. H. Dowsn5 e. citizen of the United States, and resident of Newton. in the county oi Middlesex enti State of Massaclnisetts, have invented new and izsetni inprovenients in Snap-Fasteners, which the following is ai speciiication. My invention relates to vsnep fasteners and consists' of ACertain structural improvements in the construction of the socket member.

Its object is to provide a snap fastener the parts of which are simple and readily as seinbled :ind which is strong, durable and not injnriously effected by rough usage.

Referring to the drawings Figure l is e sectional View of a portion of my improved socket niexnberfig. 2 is a. plan View of the parts shown in Fig. l, Figs. 3 and 4 are re spectively ai pien View and sectional View 'of e stud retaining' device used in Seid socket;

Fig. 5 is a pian View of a. dome used in sind socket member; Fig. 6 is a sectional View of e portion of sail socket member Showing in operative position the parts shown in Figs. 3, @i anni 5; Fig. 7 is a sectional View oi' o portion of estncl niemeer; Fig. 8 tional View of :in attaching eyelet; S) is pien View of seid eyelet; Fig. 1G shows in section stud attached to material-*g and Fig. il shows in section my improvefi sniipestener ttes-lied to material. i

A is the upper section or oep piece of my 'improved socket member and comprises e csp or shell o secured to a. disk o by clenching its edge over the latter. The disk o provided with an eyelet a2 .made integrally therewith end :Liso with radial ribs oitspokes best siioi'n in fig. These ribs perform the clonbie function of preventing the two csp pieces a., a', from turning relatively to eachother and also prevent these pieces from turning, upon the material. This is of iniportance, for it is usuel to place the naine or initials o. ininniiictnrers, or other oinzi lotion, upon the; caps oi" fasteners oli tl? s eines and it is very desirable that tire aie-sign upon the cop siieii remain goei-nienenti,7 tiie position in which it is gliicetl.l
